CROSS-REFERENCE TO RELATED APPLICATIONS

This non-provisional application claims the benefit of FrenchApplication No. 03 51119 filed on Dec. 18, 2003 and U.S. ProvisionalApplication No. 60/538,217 filed on Jan. 23, 2004, the entiredisclosures of which are incorporated herein.

BACKGROUND

The present invention relates to dispenser devices of the kind having asupport and a dispenser nozzle that is pivotally movable relative to thesupport between at least a closed position and a dispensing position, inwhich the orifice in the support coincides with the orifice in thenozzle.

In particular, the invention applies to dispenser devices that dispensefluids, especially liquids, for example, a cosmetic, including a skincare product, or a substance used for medical treatment, e.g.,dermatological treatment.

A difficulty faced by those dispenser devices is to obtain sufficientdynamic sealing between the nozzle and the support to ensure that thedispenser device does not leak, because, unlike a static seal, the sealbetween the nozzle and the support must be compatible with the nozzlemoving relative to the support.

Moreover, account must be taken of the fact that it must be possible tomanufacture the parts at a low cost price, so manufacturing tolerancesmight be relatively slack. For example, differences in dimensions arisefrom the material shrinking on cooling, from variations due to humidity,etc.

In known dispenser devices, in order to achieve leaktightness, thenozzle is pressed tightly against the support so that adequate sealingis obtained, despite manufacturing tolerances.

In order to ensure that it is not too difficult to move the nozzle,while simultaneously ensuring that the contact pressure is sufficientlyhigh, the nozzle and the support make contact via a narrow bead that isabout 1 millimeter (mm) wide, said bead going around one of the orificesof the support and one of the orifices of the nozzle, with its edgebeing contained entirely in a single plane.

The angle between the position in which orifices of the support and thenozzle coincide perfectly and the position in which they do not coincideat all, is the angle that is subtended by the arc inscribed in thediameter of the larger orifice. The smaller said arc is, the less willbe the effect on sealing quality of a small variation in the radius ofcurvature of either of the two parts, due to the manufacturingtolerances.

Thus, the devices that are found on the market are of the “open/closed”type, which means that they offer a closed position where the twoorifices do not coincide, and a single open position, where, afterpivoting through 90°, the two orifices do coincide, releasing a passagefor the fluid.

Those known dispenser devices do not offer the possibility of varyingthe angle of inclination of the nozzle relative to the support to aconsiderable extent while simultaneously allowing the fluid to bedispensed, because the angle at which the two orifices coincide must berelatively small if it is desired to maintain sealing, for the reasonsexplained above.

Therefore, there exists a need for having the advantage of a dispenserdevice that has a nozzle which can pass from a closed position to atleast two different dispensing positions, transition from the firstdispensing position to the second dispensing position taking placethrough additional pivoting of the nozzle, for example through at least30°, without thereby excessively increasing the cost price of thedispenser device, and while retaining the required leaktightness.

Moreover, dispenser devices are known through Patent Nos. GB-1,122,474,U.S. Pat. No. 4,773,801, U.S. Pat. No. 2,717,726, U.S. Pat. No.3,863,818, U.S. Pat. No. 6,390,341 and JP-4-294751, and U.S. patentapplication Publication No. 2003/0111493, each of said dispenser deviceshaving a pivotable nozzle and a support, said support comprising asealing lip with an edge that can be pressed against the nozzle. Thesedevices are designed to have only a single dispensing position.

U.S. Pat. No. 2,197,672 describes a dispenser device that includes apivotable nozzle that can assume two dispensing positions and anintermediate closed position. The nozzle includes a sealing element incork or in some other elastically deformable material that is placed insuch a manner as to block the orifice of the support through which thefluid reaches the nozzle. A sealing link in rubber or cork is pressedagainst the nozzle by a ring screwed onto the support.

U.S. Pat. No. 4,767,027 describes a measuring vessel that is able topivot relative to a support designed to be screwed onto a receptacle,for example, a receptacle containing oil, in order to mix the oil withgasoline in a predefined ratio.

SUMMARY

Exemplary embodiments of the invention provide a dispenser devicecomprising: a support having a feed orifice that can be supplied withfluid; and a nozzle that has an orifice for passing the fluid. Thenozzle may be mounted so as to pivot on the support between at least: aclosed position at which the nozzle closes the feed orifice of thesupport; a first dispensing position at which the feed orifice of thesupport communicates with an orifice of the nozzle, transition from theclosed position to the first dispensing position being effected throughrotation by the nozzle relative to the support; and, a second dispensingposition, transition from the first dispensing position to the seconddispensing position being effected by further turning of the nozzlerelative to the support. At least one of the feed orifice of the supportand the orifice of the nozzle may be provided with a flexible sealinglip that has, for example, at least when the sealing lip is notsubstantially submitted to any strain, an edge that is not entirelycontained in a single plane and that is arranged to seal communicationbetween the feed orifice of the support and the orifice of the nozzle atleast in the first and second dispensing positions.

The edge of the sealing lip may, for example, extend about a pivot axisof the nozzle relative to the support over an angle of at least 45°. Forexample, edge of the sealing lip may extend over an angle of at least60°, and, for example, about 90°.

Since the edge of the sealing lip may have a relatively wide angularmovement around the pivot axis of the nozzle, at least two dispensingpositions are allowed that correspond to totally different orientationsof the nozzle, for example, the first position being after the nozzle ispivoted about 45° relative to the closed position and the secondposition after said nozzle is pivoted for a further 45°.

According to various embodiments, the user may benefit from at least twodispensing positions in which the nozzle has a different orientationrelative to the support without there being any concern about leakagedue to manufacturing tolerances as a result of eliminating manufacturingclearance through the sealing lip. Said sealing lip may allow fordynamic sealing without the necessity of securing the nozzle so tightlythat its rotation is obstructed unnecessarily.

For example, a plurality of dispensing positions makes it possible todispense the fluid when the longitudinal axis of the nozzle is atsubstantially 45° with the axis of the receptacle onto which the supportis mounted, so that, for example, a hair product may be spread over theback of the head. Then, the nozzle may be pivoted so that itslongitudinal axis is substantially parallel to the longitudinal axis ofthe receptacle, so that, for example, the fluid may be spread all overthe head of hair.

The pivot axis may be substantially perpendicular to the longitudinalaxis of the receptacle. Advantageously, the sealing lip may be made of asame material as the support, preferably made integrally, i.e.,monolithically with said support, which enables manufacture at a lowprice. The lip may be molded thin enough to conform locally to anyvariation in the manufacturing gradients of the nozzle, in order toaccommodate manufacturing clearance.

The sealing lip may taper toward its edge, which may increase itsdeformability. For example, the lip may have a triangular cross-section.The lip may be on an incline relative to an axis of the support and, forexample, may slope toward an inside of the feed orifice of the support.

The edge of the sealing lip may extend substantially over a circularlycylindrical surface. For example, said cylindrical surface may have agenerator that is parallel to the pivot axis of the nozzle.

The sealing lip may be supported by a bead, for example, that extendsparallel to an axis of the support. For example, the bead may extendparallel to an axis that corresponds to an unmolding direction of thesupport.

For example, the support may include an assembly skirt that enables thesupport to be secured to a receptacle. For example, the assembly skirtmay enable the support to be secured to a neck of the receptacle. Theskirt may have, for example, an inside thread. The axis of the supportmay correspond to the axis of said assembly skirt.

The support may also have a sealing lip that is configured to be pressedin a leaktight manner against an inside surface of the receptacle, forexample, the inside surface of the neck.

The support may also have an outside covering skirt that is connected ata top thereof to the assembly skirt.

The orifice of the nozzle may open out in a cylindrical surface of thenozzle. The cylindrical surfacing may have a generator line that issubstantially parallel to the pivot axis. The nozzle may be a singlepiece.

The support may include a notch for receiving a pipe of the nozzle whensaid nozzle is in the closed position. Said notch may be configured toallow the pipe to be snap-fastened thereto, which may make it easier forthe nozzle to remain in a closed position, for example, when beingcarried.

The support may include housings for receiving two opposite studs of thenozzle so as to hinge the nozzle to the support. Said housings may bemade to allow said studs to be snap-fastened thereto.

The support may also have at least a first portion in relief that isarranged to cooperate with a second portion in relief that correspondsto the nozzle. The cooperation of the first and second reliefs maygenerate at least one hard point in the turning of the nozzle at apredetermined orientation of the nozzle relative to the support.

The first portion in relief may comprise, for example, a tab madeintegrally, i.e., monolithically with the support. The tab may include atooth arranged to be pressed against the nozzle in order to curbpivoting by said nozzle. The second portion in relief may comprise, forexample, a recess made in the nozzle, for example, at the base of thepipe thereof. The tooth may become engaged in said recess when thenozzle is in a maximally pivoted position.

In various exemplary embodiments, the fluid may be dispensed withoutleaking in each dispensing position.

Preferably, the feed orifice of the support and the orifice of thenozzle extend about a pivot axis of the nozzle relative to the support,respectively over a first angle and a second angle. The second angle maybe different from the first angle, with, for example, the angleassociated with the orifice provided with the sealing lip being largerthan the angle associated with the other orifice, e.g., being twice aslarge.

In exemplary embodiments, the entire section of one of the feed orificeof the support and the orifice of the nozzle opens out into the otherone of the feed orifice of the support and the orifice of the nozzlewhen the nozzle is in each of the dispensing positions.

One of the feed orifice of the support and the orifice of the nozzle mayopen out advantageously into the other one of the feed orifice of thesupport and the orifice of the nozzle (provided with the sealing lip)inside the outline of said lip, at least when the nozzle is in one ofthe dispensing positions, preferably in each dispensing position.

In exemplary embodiments, at least one of the support and the nozzle mayhave an annular bead with an edge that is not contained entirely in asingle plane. The sealing lip may be connected to said edge of theannular bead.

Exemplary embodiments of the invention provide a method for applying afluid product to hair. The method may comprise: using a dispenserdevice, such as defined above, to apply fluid to a back of a head whilea pipe of the nozzle is orientated at substantially 45° relative to thelongitudinal axis of the receptacle; using the dispenser device to applythe fluid to the head while the pipe or dispensing tube of the nozzle issubstantially parallel to the longitudinal axis of the receptacle.

Exemplary embodiments of the invention provide a dispenser device thatcomprises: a support having a feed orifice that can be supplied with afluid; and, a nozzle that has an orifice enabling the passage of fluid.The nozzle may be mounted so as to pivot on a support around a pivotaxis between at least: a closed position at which the nozzle closes thefeed orifice of the support; a first dispensing position at which thefeed orifice of the support communicates with the orifice of the nozzle,transition from the closed position to the first dispensing positionbeing effected through rotation by the nozzle relative to the support;and, a second dispensing position, transition from the first dispensingposition to the second dispensing position being effected throughfurther rotation by the nozzle relative to the support, the feed orificeof the support being provided with a sealing lip that is deformable. Thesealing lip may be flexible, and may be made of a same material as thesupport.

Exemplary embodiments of the invention provide a packaging and dispenserdevice that comprises: a receptacle that contains a product to bedispensed; a support that has a feed orifice that can be supplied withfluid contained in the container; and, a nozzle that has an orificeenabling the passage of fluid. The nozzle may be mounted so as to pivoton the support around a pivot axis between at least: a closed positionin which the nozzle closes the feed orifice of the support; a firstdispensing position at which the feed orifice of the supportcommunicates with the orifice of the nozzle, transition from the closedposition to the first dispensing position being effected throughrotation by the nozzle by about 45° relative to the support; and, asecond dispensing position, transition from the first dispensingposition to the second dispensing position being effected throughfurther rotation by about 45° by the nozzle relative to the support.

DETAILED DESCRIPTION OF EMBODIMENTS

FIGS. 1 to 3 show an exemplary packaging and dispenser device 1 thatcomprises a receptacle 2 of elongate shape, and a dispenser nozzle 4that can turn relative to a support 3 about a pivot axis 4 that isperpendicular to the longitudinal axis X of the dispenser device 1.

As shown in FIG. 5, the support 3 may comprise an assembly skirt 6, thatis tubular about an axis X, that is internally threaded, and that isscrewed onto a threaded neck 7 of the receptacle 2.

Sealing may be obtained between the support 3 and the neck 7 of thereceptacle by an annular sealing lip 9, for example. The sealing lip 9may be pressed against a radially inner surface 10 of the neck 7.

The assembly skirt 6 and the annular lip 9 may be connected to a topwall 12 of the support 3. The top wall 12 may be extended downward at aperiphery thereof by a covering skirt 13, which may extend substantiallydown to the base of the neck 7.

A housing 16 may be formed in the support 3 in order to receive a baseportion 17 of the nozzle 4. The base portion 17 may have a dispensernozzle 18 of longitudinal axis Y, that defines a channel 20 via whichfluid contained in the receptacle 2 can be brought to an outlet orifice21.

As shown in FIG. 4, the housing 16 may be defined laterally, forexample, by two side walls 24 each having a respective housing 25 forreceiving a respective cylindrical stud 26 on the base portion 17 inorder to allow the nozzle 4 to pivot relative to the support 3 aroundthe pivot axis R. Said pivot axis R may coincide with the axis W of thestuds 26.

Each housing 25 may have a tapering top opening 28, which enables thestuds 26 to snap into said housings 25 when the nozzle 4 is brought downonto the support in the direction of the arrow M in FIG. 4 for assemblypurposes. As shown in FIG. 4, the support 3 may include a notch 30 in atop face thereof for receiving the dispenser nozzle 4 when the axis Y ofsaid dispenser nozzle is substantially perpendicular to the longitudinalaxis X. The notch 30 may be defined by an indentation of the top wall 12and may have two studs 33 on flanks thereof that help to hold the nozzle4 in the notch 30. The notch 30 may provide a hard point when thedispenser nozzle 4 pivots about the pivot axis R in order to be broughtto a dispensing position.

The bottom of the housing 16 may be defined by a wall 38 which generallyextends perpendicularly to the axis X and which connects, at a peripherythereof, to the annular lip 9.

A feed orifice 40 for feeding the nozzle 4 with fluid may open out intothe housing 16. As shown, said feed orifice 40 is not an orifice ofcircular section contained in a plane, but is defined by the free edge41 of a sealing lip 42, said edge 41 corresponding to the tip of the lip42. At a base thereof, said lip 42 may be connected to a bead 43 whichextends parallel to the axis X. The bead 43 may be supported by the wall38, as shown in FIG. 5.

The edge 41 is not entirely in a single plane and the feed orifice 40may extend about the axis R in an angle α of about 90°, for example, asshown in FIG. 6.

As shown in FIGS. 6 and 7, the lip 42 may be directed toward an insideof the feed orifice 40 and toward an outside of the housing 16, so thatsaid lip 42 may be pressed, with elastic deformation, against acircularly cylindrical surface 45 about the axis Z at the base portion17 of the nozzle 4, so as to ensure that contact between the support 3and said surface 45 is leaktight. The lip 42 may also make it possibleto accommodate manufacturing clearance, and, for example, to compensatefor any variation in the radius of curvature of the surface 45.

When observed in cross-section as shown in FIG. 7, the lip 42 may extendalong an axis W that makes an angle of about 45° with the axis X.

Said cross-section may be triangular as shown, and the base of said lip42 may connect to an inside 43 a of the bead 43 at a base thereof.

The channel 20 of the nozzle 4 may open out in the surface 45 via anorifice 48.

As shown in FIG. 4, for example, the support 3 may also include a tab 50that is elastically deformable, said tab extending along the axis X. Thefeed orifice 40 may be situated between said tab 50 and the notch 30.

A reinforcing web 52 may extend parallel to the axis X and parallel tothe axis of the notch 30 between the tab 50 and a wall 53 which extendsthe annular lip 9 upward, said wall 53 delimiting the housing 16 on theother side of the notch 30.

The tab 50 may be provided with a tooth 54 which presses against thesurface 45 of the nozzle 4 when said nozzle is in the closed position,as shown in FIG. 8.

The base portion 17 of the nozzle may include a recess 60 at the bottomof the pipe 18, said recess 60 being formed at the junction of aprotuberance 51 on the pipe 18 and the surface 45.

The tooth 54 may be engaged in the recess 60 when the longitudinal axisY of the nozzle 4 is substantially parallel to the longitudinal axis X,as shown in FIG. 10. In this position, the protuberance 51 may comesubstantially against the top 58 of the tab 50.

When the longitudinal axis Y of the nozzle 4 is oriented substantiallyperpendicular to the longitudinal axis X of the receptacle 2, as shownin FIGS. 1 and 8, the orifice 48 may open out outside an outline of thelip 42, above the orifice 40, so that the channel 20 is not fed withfluid, and the receptacle is substantially closed, for example, in ahermetically sealed manner by the surface 45.

When the nozzle 4 pivots through 45° from the closed position, in thedirection of the arrow O in FIG. 8, the orifice 48 may open out facingthe feed orifice 40 within the outline of the lip 42, and fluid canreach the channel 20 of the nozzle 4, as shown in FIGS. 3 and 10.

Lastly, when the nozzle 4 is brought to a maximally pivoted positionthereof, as shown in FIGS. 2 and 9, the orifice 48 may always open outfacing the feed orifice 40 inside the outline of the lip 42.

For example, the maximally pivoted position shown in FIG. 9 may be usedto apply fluid to a head of hair, whereas the position shown in FIG. 10may be used to dispense fluid on the nape of the neck.

Of course, the invention is not limited to the embodiment describedabove.

For example, the feed orifice 40 and the lip 42 may be given othershapes, if, for example, it is desired to alter the zone where the feedorifice 40 and the orifice 48 coincide and to dispense fluid from thenozzle, while said nozzle is in an angular position relative to thesupport that is different from the positions shown in FIGS. 9 and 10.

It is also possible to alter the dispenser nozzle 4 and, for example, toprovide said nozzle with a plurality of outlet orifices through whichthe fluid is dispensed, said orifices opening out, if necessary, betweenthe teeth of a comb.

The receptacle 2 may have a wall that is flexible or inflexible. Forexample, as shown in FIGS. 1 to 3, when the receptacle has a flexiblewall, the receptacle may have a wide base. Other shapes are possible,and, for example, the receptacle may come in the shape of a tube.

The support 3 may be secured to the receptacle 2 other than by screwfastening. For example, the support may be snap-fastened, or may be madeat least in part integrally, i.e., monolithically with the receptacle.

Guiding marks may be made on the nozzle and/or the support to indicateto the user the different angular positions of the nozzle that arepossible or recommended.

The lip 42 may be made on the nozzle, if necessary, optionally bymodifying said nozzle so as to make it possible for the lip to be madeby molding a plastics material. The feed orifice 40 may then be borderedwith a circularly cylindrical surface against which the lip would bepressed.

Throughout the description, including in the claims, the term“comprising a” must be understood as meaning “comprising at least one,”unless specified to the contrary.

Although various exemplary details have been described with reference toparticular embodiments, it is to be understood that these embodimentsare merely illustrative of the principles and applications of thepresent invention.
